Description

Description: INDUSTRIAL APPLICABILITY The present invention enables a caller to directly check the current remaining number of a prepaid card by voice when the electronic exchange manages the prepaid calling. The present invention relates to a residual number inquiry device for an electronic exchange.

2. Description of the Related Art In the conventional remaining number inquiry method in an electronic exchange, a display device is added to a caller's telephone, and the remaining number is inquired using this display device.

FIG. 2 shows an example of the configuration of a conventional electronic exchange. In FIG. 2, 1 is a telephone with an indicator, 7 is an electronic exchange, and an extension control device 2 for controlling the telephone 1 and a communication path 3 are provided.
Central control unit 4, local line control unit 5, residual number management unit 6
It consists of and. Here, the central controller 4 controls the extension controller 2, the communication path 3, and the station controller 5.

Next, the operation of the above conventional example will be described. In FIG. 2, when the telephone set 1 makes a station line call, the central control unit 4 detects this signal via the extension line control unit 2 and confirms that it is a station line call. Next, the central controller 4 executes a normal line acquisition operation via the line controller 5,
The remaining number management device 6 is notified of the start of the remaining number operation.
The remaining number management device 6 detects the remaining number of the prepaid card and reports it to the central control unit 4, and the central control unit 4 displays the remaining number on the display of the telephone 1. In the central control device 4, when the residual number is not 0, the central line control device 5 connects the central line and the telephone set 1 via the extension control device 2. The remaining number management device 6 notifies the central control device 4 of the remaining number each time the remaining number changes,
The central control unit 4 displays the residual number on the display of the telephone 1 via the extension control unit 2.

As described above, even in the above conventional electronic exchange, it is possible to manage the outgoing call by the prepaid system.

SUMMARY OF THE INVENTION However, the conventional remaining number inquiry method for the electronic exchange described above has a problem that a display device must be added to the calling side telephone.

The present invention solves such conventional problems,
It is an object of the present invention to provide a remaining number inquiry device for an electronic exchange, which enables inquiry of the remaining number without selecting the type of telephone.

Means for Solving the Problems In order to solve the above problems, the present invention provides a telephone that pays a call charge by a user inserting a prepaid card in which a remaining number is stored, and a telephone and a line. The electronic exchange to be connected and the electronic exchange housed in this electronic exchange, each time the above-mentioned telephone makes an office line, the remaining number of the prepaid card is detected, and the prepaid according to the call time until the remaining number becomes "0". The remaining number management device for reducing the remaining number of cards, a storage device which is stored in the electronic exchange and stores a specific telephone number as a special number for inquiry of the remaining number, and a storage device which is stored in the electronic exchange and stores the remaining number management device. A voice synthesizer for converting the residual number data into voice and outputting the voice, and when the telephone number from the telephone matches the telephone number of the storage device, the output signal of the voice synthesizer to the telephone number. And a central control device for outputting.

Therefore, according to the present invention, even if the calling side telephone does not have a display, the remaining number of the prepaid card of the caller can be confirmed by voice by dialing the number instructing the remaining number inquiry of the prepaid card. It has the effect that

Examples Hereinafter, examples of the present invention will be described with reference to the drawings. FIG. 1 is a schematic block diagram showing an embodiment of an electronic exchange using the remaining number inquiry method of the electronic exchange according to the present invention. In FIG. 1, the same parts as those in the conventional example shown in FIG. 2 are designated by the same reference numerals. That is, 1 is a telephone, and 12 is an electronic exchange, and an extension control device 2, a communication path 3, a central control device 14, and a central line control device 5 that control the telephone 1.
The remaining number management device 6, the voice synthesizer 7, and the remaining number inquiry special number storage device 8 are included. Here, the telephone 1 may be of a type not provided with a display. Also,
The central control unit 14 controls the extension control unit 2, the communication path 3, the office line control unit 5, the remaining number management unit 6, the voice synthesizing unit 7, and the remaining number inquiry special number storage unit 8, respectively.

Next, the operation of the embodiment shown in FIG. 1 will be described. That is, when the telephone number 1 dials the remaining number inquiry special number, the central control unit 14 detects this signal through the extension control unit 2 and searches the remaining number inquiry special number storage unit 5.
As a result of the search, when the central control unit 14 confirms that the dial transmission is the remaining number inquiry special number, the remaining number management unit 6
Request the remaining count information on the sender's prepaid card. The remaining number management device 6 detects the information indicating the remaining number of the prepaid card and reports it to the central controller 14. The central control unit 14 receives the remaining number information from the remaining number management unit 6, notifies it to the voice synthesizing unit 7, and further connects the extension circuit and the speech path of the voice synthesizing unit 7. As a result, the residual number information by voice transmitted from the voice synthesizer 7 is transmitted to the telephone 1.
Be notified to.

Thus, according to the present embodiment, by dialing the remaining number inquiry special number, the remaining number can be known by voice regardless of the type of telephone set.

When the present invention is applied to a dormitory or a hotel, a prepaid telephone system can be introduced at a relatively low cost without replacing the existing telephones in each room.

EFFECTS OF THE INVENTION As described above, according to the present invention, since the remaining number notification is performed by voice, the remaining number inquiry notification can be performed even if the calling side telephone does not have a display. Therefore, for example, it is possible to notify the remaining number of inquiries to the visually impaired.
